If you care about data and space, you wouldn't use either.
These are are about uptime not data protection or storage efficiency. You appear to want to use RAID/JBOD for the exact opposite reasons one would actually want to use these solutions.
Asking whether RAID or JBOD is better for data recovery is a bit like asking what brand of lawnmower is best to use to commute to the office.
i do know that, the reason for why i opened this thread is that i'm trying to cover all scenarios,
◼ i have 2 Hardware RAID Storage, one is on site and the other is offsite, the first one is for daily use, and the second one i use it as backup
◼ the first RAID storage is 5-bay (More bays = more space) , in this raid storage 4-HDDs will be enough so i loaded the fifth HDD and set it on RAID 5 to provide protection (fault tolerance)
◼ the second RAID storage is 4-bay, (less bays = less storage) i don't have enough bays, so since i don't have enough bays/space to use RAID 5 i'm forced to use RAID 0 or JBOD, i'm planing to use it as backup and keep it in another site
◼ in case of unit failure and the raid system is not broken i confirmed that when one of the units fails i can buy a new unit (same model) and then insert the drive in the same order and it will work again!
◼ finally in case something wrong happened to the JBOD Storage , i want to make sure that things remain simple and easy for me to recover data, from what i read RAID is much harder in data recovery.
So i do have a RAID 5 storage and i do have an offsite backup i just wanted to cover all scenarios and learn more
any advise is appreciated
thanks
